Abstract


In recent years, along with the rising of the computer performance, network bandwidth and green computing, virtualization technology has become more and more important in resource integration and security isolation, become the focus of academia and industry. Desktop virtualization is currently the research hotspot of virtualization. Around the desktop virtualization of user experience, academia and industry have done quite a lot of research work. However, key technologies of desktop virtualization system are still faced with many challenges: how to implement the idea of improving the accessibility of system, how to design a multi window integration mechanism with efficient graphics compression method in order to improve the user experience, etc.This problem is solved by an innovative web-based desktop virtualization system. Its core design idea is: To integrate network applications and local desktop application into a virtual work environment, and use the browser to login. Users on the platform can use Internet applications provided by third party providers. Also they can use native desktop applications. Main techniques as follow: Deploy an user requests center to handle user requests, connect the client with the application server; Use JavaScript to construct a user interface framework, integrate multi applications into one page; Capture window image update in the background, use application transmission unit to transmit the screen update to the client; Use the window synchronous technology to synchronize windows between client and server; Migrate the data transmission channel to physical machine, in order to optimize the image transmission performance by directly read screen update of virtual machine from memory.In order to validate the function of WebDesk and tests its performance, we designed a cluster environment of real hardware, and established a complete experimental security office environment through the deployment of desktop virtualization system. Function tests show that, WebDesk can fully realize the window image transmission and window control operations, integrate network application services and native desktop applications, and realize the function of network integration office. Performance tests show that, in WebDesk, the average type latency is about 52ms, the average image transmission latency is about 190ms, and the quality of video playback is about 82.7%。
